| 摘 要： | 提出了一种将秘密语音隐藏到载体语音的新方法,并引入 Logistic 混沌映射,利用混沌序列对秘密语音信息进行处理。算法根据人耳对音频倒置不敏感和音频幅度值为正的采样点在总采样点中所占的比例比较稳定的特点,通过倒置的方法调整该比例的大小嵌入秘密信息。实验表明,含有秘密信息的混合语音不仅具有良好的不可感知性,而且对诸如噪声、低通滤波、重采样等攻击具有良好的鲁棒性。

| Abstract: | This paper proposed a kind of new approach of hiding speech into the audio carrier.Utilized Logistic chaotic map as chaotic sequence to process the secure speech.Based on the features that audio sample dots inversion had little influence on the human hearing and that the percentage of the positive audio sample dots in a period of time was robust against some audio attacks,embedded the secret information to the audio by adjusting the percentage of the positive audio sample dots.Realized the adjustment by inv... |
